The coated plate is now immersed in a bath composed of one hundred grains of cyanide of potassium, one dram of acetic acid, No. 8, and twenty ounces of water. The acid operates to toughen (No specimens) while the cyanide of potassium loosens said film from its plate and permits of its separation therefrom in a fraction of the time which 0 would otherwise be required.
